Method for producing thermoplastic golf ball material, and golf ball having thermoplastic material

摘要

The thermoplastic golf ball material comprises (a) an unneutralized copolymer of ethylene and at least one of acrylic acid and methacrylic acid having from about 5 weight percent to about 12 weight percent acid monomer; (b) Combining and reacting a metallocene-catalyzed copolymer of ethylene and octene; (c) an unsaturated fatty acid; and (d) a sufficient amount of a metal cation to neutralize about 65% to about 90% of the acidic groups. Made by manufacturing ionomer thermoplastic materials. The ionomer thermoplastic material can be used in the core, cover, or layer between the core and cover of the golf ball.
